I don't know specifically about your case, but on one motherboard I had, turning off the allow_memio fixed my problems completely. Apparently on the 3940, some MB BIOS's don't initialize the PCI bridge correctly. Or ast least, I think that was a simplification of what Justin once told me. In any case, since I stopped using MEMIO for this particular MB, it's worked fine.
